Polaris B is always a target every night I'm out there observing. I was disappointed that I could rarely see it with my Vixen 80ED. In the past few nights I have been able to see it with the WO66 and AT66 even with a bit of Moon out. I think that the difference is in the magnification ..... I was trying "too hard" before. It actually seems to be easiest around 40x - 50x. If you haven't tried it yet, take a look, it's a pretty pair with the companion being so dim.

Antonino, Years ago, using a TeleVue Ranger(70mm), I made a number of observations of Polaris with various apertures and magnifications to see how easily seen the companion was. If I can find my notes I'll post them. You might try it and see what results you get.

I have seen the companion many times with my Vixen 60 mm f/11.7 at 60X. It is usually easy with my Vixen 80 mm f/11.4 at 51X.

I do nearly all my observing from my yard. Most of the year a bunch of trees in my back yard screen the North Star from my view. But it's visible in winter and I have made a few observations with a 4" refractor a while back. It was a nice split at about 110X, the companion showing a soft bluish tint. I'll have to try it with my 5" refractor....
